Abstract

In general, this disclosure is directed to techniques for memory efficient and low complexity adaptive variable length coding (VLC) of data for a variety of applications, such as coding of digital video, image, audio, or speech data. In some aspects, the techniques may exploit properties of particular sets of codewords to support very compact data structures. In other aspects, the techniques may support low-complexity, adaptive encoding and decoding of binary sequences produced by memoryless sources.
